3 Claims. (6i. MAP-14d) l The present invention relates to powered shovels and is more particularly concerned with a shovel mounted on a tractor with Caterpillar or -endless treads.

The primary object of the invention is to pro= vide a device of the character referred to which is especially adapted to move or load manure.

Another object of the invention is to provide a device of the character referred to which will load manure on a manure spreader from the ground where it has been dropped by animals or piled by laborers.

A further object of the invention is to provide a device of the character referred to of simpler and more compact construction than prior devices.

With the foregoing and other objects and advantages in view the invention consists of the novel construction and arrangement of parts hereinafter described and claimed.

In. the accompanying drawings illustrating the invention,

Figure l is a side elevation of the machine.

Figure 2 is a top plan view thereof.

Figure 3 is a front elevation of the shovel.

Figure l is a rear elevation of the machine.

Figure 5 is a vertical longitudinal section of the shovel on line 55 of Figure 2.

Like numerals, as used in the description and drawings, designate the same parts of construction.

it isa powered tractor of conventional type which is mounted on Caterpillar treads ll.

' Secured to the rear of the tractor body is a transversely disposed yoke l2 whose depending, parallel arms provide support for an horizontally disposed frame it, consisting of an end bar and two forwardly projecting, parallel side bars. These side bars are bifurcated on the front ends, as at it, for reception of the rear ends of parallel shovel holding arms D5 which are mounted on pivot bolts l6 to allow a swivel movement of the arms in a vertical plane.

The shovel I1 is pivotally attached to the forwars ends of said arms by means of brackets It and bolts. It is constructed with an horizontal bottom I9 provided with a plurality of spaced,

parallel teeth 20, a vertical back and flared sides a) to make said shovel yieldable and it is connected to a standard .on shovel arm it by means of a pivoted bolt 28 and to a bracket on the back of the shovel by another pivoted boltfl't. The spring it returns shovel M to loading position after dumpins.

Projecting rearwardly from the yoke 62 is another yoke 8b which is supported by standards 35. Suspended from this yoke is the housing 82 for a divided shaft powered by the tractor engine. On one end of the shaft is mounted a controlled brake 33 and a controlled clutch lid is mounted on the other end. The control lever 35 for oper-- ating said elements is provided with a crank arm and the handle thereof is near the drivers 'seat.

Mounted on said shaft is a cable drum 86 with a deep one-strand groove which operates a cable to a second cable drum 3?, with a similar groove, mounted on a rotatable shaft 88 which is journaled in the depending branches of yoke l2. This shaft projects at each end beyond the yoke and mounted on these projecting ends to rotate therewith are dual cable 5 39 carryi g cables to which are pivotally attached at the free ends to the upper ends of standards 6i mounted perpendicularly on the rear ends of the shovel arms id. Brace bars d2 extend from said standards to the foreparts of the arms.

In operation the lever is operated to throw in the clutch and raise or lower the shovel. By use of the brake the upward and downward movement thereof can be controlled. When the shovel is lowered to contact the ground the Caterpillar is moved forward and the shovel thereby driven into the bottom of the manure pile. With the shovel filled, the motion of shaft 38 is reversed to raise the shovel. The operator then dumps the load by pulling on cable 2% and tilting the shovel. The shovel load may be dumped in a transport or it may be carried to'another point by the Caterpillar.

As different embodiments may be made of this inventive concept and modifications may be made in the embodiment hereinbefore shown and described, it will be understood that the matter herein is to be interpreted as illustrative merely and not in a limiting sense.

What I claim is:

1. In a manure loader adapted to be mounted on a Caterpillar tractor, a frame dependingly carried by said tractor, a painof longitudinallyextending shovel-holding arms pivotally secured at one end to the outer end of said frame, a shovel pivotally secured to the other ends of said arms, a yoke disposed rearwardly of said shovel and secured to the latter, a truss arranged transvereely with respect to said shovel arms' and secured to the latter, a standard on said truss, a crank lever mounted in said standard and operatively connected to said yoke for tilting said shovel, resilient means operatively connected to said shovel and said shovel arms for returning said shovel to .its normal position upon release oithe load, and means for raising and lowering said shovel.

2. In a manure loader adapted to be mounted on a Caterpillar tractor, a' frame dependingly carried by said tractor, a pair of longitudinallyextending shovel-holding arms plvotally secured at one end to the outer endsof" said frame, a

shovel pivotally secured to the other ends of said arms, a yoke disposed rearwardly of said shovel and secured to the latter, a truss arranged transversely with respect to said shovel arms and secured to the latter, a standard on said truss, a crank lever mounted in said standard and operatively connected to said yoke for tilting said shovel, resilient means operatively connected to said shovel and said shovel arms for returning said shovel to its normal position upon release 25 1,742,494

of its load, means on said frame for actuating said crank 1ever,-and means for raising and low ering said shovel.

'3. In a manure loader adapted to be mounted on a Caterpillar tractor, a frame carried by said 4 1 tractor. a pair of longitudinally-extending shovelh'olding arms pivotaliy secured atone end'to the "outer end of said frame. a shovel pivotaily secured to the other ends of said arms, a yoke disshovel.
